Hi-Tech
Equipment Helps Trailblazing Caithness Scientists
PRESS
& JOURNAL (IAIN GRANT) 14 July 2004
Sophisticated new
detection equipment worth £200,000 is enabling a team of Caithness-based
scientists to embark on a number of trailblazing projects.
Scientists at the Environmental Research Institute (ERI)
have embarked on a project to establish if seaweed in the Highlands
could be a source of natural antibiotic drugs.
And another pioneering study is seeking to gauge the amount of used
medicines which may find their way into Scottish reservoirs.
A cosmopolitan
team of post-graduates based at the ERI's base in Castle
Street in Thurso is carrying out the research under the guidance of
research director Dr.Stuart Gibb and his colleagues.
They include
five young scientists recruited from more than 650 who applied from
UK and abroad to fill the posts.
The
ERI is part of North Highland College
and is gearing towards playing a major part in the college's role within
the planned University of the Highlands and Islands.
New equipment comprises a high-resolution chromatographic mass spectrometer
which can break down complex mixtures and identify and quantify individual
components.
Dr Gibb said: "It's the most sensitive technology
available to research scientists today."
Used to uncover drugs cheats in sport, the machine can process a vast
array of natural compounds, including herbicides, pesticides, drugs
and vitamins.
It operates at the level of nanogrammes per litre, which means that
it could pick up and identify a teaspoonful of material in a tank the
size of 1000 Olympic-size swimming pools.
The German-made machine was funded by the UHI Millennium Institute,
the European Regional Development Fund, the UK Strategic Infrastructure
Fund and Caithness and Sutherland Enterprise.
And
in another project, Swiss post-graduate student Diane Ruchonnet
is in the throes of examining seaweed samples taken from Thurso beach.
Her quest is to expose particular constituents of the seaweed to bacteria
to establish whether they could be harvested to serve as an antibiotic.
Dr Gibb said the project is particularly exciting as
it could potentially create an opening for a new local business.
He said: "In a lot of the projects we have started up, we have
an eye on the commercial opportunities that could be developed. We are
very keen to make a contribution towards the sustainability of the area
and the local economy."
And he stressed the seaweed project shows the merit of having an environmental
institute in the far north.
Dr
Gibb added: "One of the main advantages of having the
institute in this area is that we have such wonderful natural resources
on our doorstep. Where better to site an environmental lab?" Spaniard
Carolina Nebot is carrying out the first study in Scotland
to monitor for the presence of prescribed drugs in Scottish waters.
It follows a re-assessment of the potential risk associated with traces
of used drugs, such as antibiotics, steroids, hormones, analgesics and
tranquillisers resurfacing in the human environment.
Of particular
concern are pain-killers and anti-inflammatory and anti-epileptic drugs
which are not fully broken down by sewage treatment.
